IMPROVEMENT IN CURTAIN-FIXTURES.

Specication forming part of Letters Patent No. 157,489, dated December8, 1874; application filed March 5, 1874.

CAsE B.

To all whom it may concern:

Beit known that we, OHAUNOEY BUOKLEY and LODOWICK L. SAWYEE, of Meriden,in the county ot' New Haven and State of Connecticut, have invented anew Improvement in Curtain-Fixtures; and we do hereby declare thefollowing, when taken in connection with the accompanying drawings andthe letters of reti erence markedthereon, to be a full, clear, and exactdescription of the same, and Which said drawings constitute part of thisspecilication, and represent, in-

Figure l, a top view; Fig. 2, an end View, and in Fig. 3, a'longitudinalsection.

This invention relates to an improvement in the device for which LettersPatent of the United States were granted to Chauncey Buckley, (one ot'these applicants,) dated February 1S, 1873, the object of the presentinvention being to simplify and cheapen the construction; and itconsists in making the barrel of the pulley and one head, the screw, andpivot in one piece, the other head of the pulley serving as thefriction-plate, all as more fully hereinafter described.

A is theroll; B, a disk or plate lyingagainst the end of the roll, itsedge provided with one or more teeth or notches, a. C is the other headof the pulley, on which is formed a pivot or trunnion, d; and upon theinside of this head the barrelD is formed, and on the barrel a threadedscrew, E, a shoulder, f, being formed between the barrel and the screw.The screw is passed through the plate B into the roll; and between theshoulder f and the plate B the friction disk or plate l is placed,

'so that the bearing or friction upon the plate B may be adjusted byturning the screw E to a greater or less distance into the roll. E isthe bracket, in which is an elongated seat, F, for the pivot d to restin; and from the bracket an arm, G, extends in, as seen in Fig. l, so asto engage a tooth or notch on the -plate B, which will hold the roll tosupport the curtain in any position; but the friction on the plateyields, so that taking hold of the curtain it may be drawn down, theroll turning While the plate B remains stationary, and the turning ofthe roll Wlnds the cord upon the barrel D; then, when the cord is drawnupon to Wind the curtain, the roll moves forward in the elongated seatF, so as to free the plate B from the arm G, and prevent any friction orobstruction in Vrolling up the curtain, this Voperation beingsubstantially the same as in the Buckley patent before referred to.

We do not claim any ofthe parts described,

except as in the combination hereinafter specied, the parts inthemselves being old.

We claim as our inventionrlhe combination otthe roller A, barrel D,toothed plate B, and friction-plate t, substantially as set forth.
